, integration is necessary to calculate the work done. the work done by a constant force of magnitude f, as we know, that displaces an object by Δx can be given asl: w = f.Δx in the case of a variable force, work is calculated with the help of integration. for example, in...
work done displacement: displacement is a vector quantity that gives the shortest distance between the initial and final positions of any object. if the resulting displacement in the direction of force due to force acting on any object is zero, the net work done by that force on that object ...
If you don't want to use a calculator, you can also calculate the upper and lower bounds using the chi square critical value in R using the formulas here. #for 95% (0.95) confidence interval #where x is the number of observed events lower_bound <- qchisq((1-ci)/2, 2*x)/2 uppe...
There is no practical reason to memorize digits of π, other than that you’re calculating something by hand and don’t want to waste time looking them up. In that case there’s not much call go to past 3.14. If you need more than about 3.14159, get a calculator to do it. But ...
Simple calculations for just about any calculator. The cut diagram shows how simple the geometry is – a rectangle for the plate, and a second rectangle split on a bias for the two legs. This is very easy to create in Inkscape. But, I had several to do and more to do in the future...

To give you an example of an extremely simple JavaScript calculator, the HTML below shows you how to create a Fahrenheit to Celsius converter using JavaScript: <!-- hide this script from old browsers function temp(form) { var f = parseFloat(form.DegF.value, 10); var c = 0; c ...
Recalibrating a speedometer can be done by manipulating the hairspring, the permanent magnetor both. Generally, the strength of the magnetic field is the easiest variable to change. This requires a powerful electromagnet, which can be used to adjust the strength of the permanent magnet in the ...
Yeah! Actual real NAPLPS made by me! NAPLPS— an almost-forgotten videotex vector graphics format with a regrettable pronunciation (/nap-lips/, no really) — was really hard to create. Back in the early days when it was a worthwhile Canadian initiative called Telidon (see Inter/Access’s...
